RICS Level 2 and Level 3 surveys for homes in Calstock, Cornwall, with local data on age, flood, radon and listed buildings.
Our suggestion for Calstock
In Calstock, we'd usually point buyers to a Level 3 Building Survey. With so much older, solid-walled stock, the deeper inspection and repair advice of a Level 3 usually pays for itself. A Level 2 can still suit a newer, conventional home.
In 2025, 19 homes sold in Calstock at a median price of £270,000, down 2% on 2024's £275,000.
| Type | Median |

45% of the housing stock in these neighbourhoods dates from before 1919 and 44% from before 1900. Expect solid walls rather than cavities, so damp diagnosis needs care: cement renders, plastic paints and raised ground levels trap moisture in walls that were designed to breathe.

Calstock lies inside the Cornwall and West Devon Mining Landscape World Heritage Site. Cornwall's mines left shafts and workings that aren't all mapped, which is why a mining search comes as standard here; pre-1950 concrete homes also raise the mundic question.
